Abstract

Methods and apparatuses for managing inter-satellite handovers are provided to allow a user terminal to reduce the frequency of handovers while maintaining a sufficiently high system capacity in a non-geosynchronous satellite communication system. The method and apparatus for managing inter-satellite handovers may be implemented in a gateway, in infrastructure connected to a gateway, in a user terminal, or in a satellite.
